         is improve/increase mold manufacturing use property can, hot process is commonly used methods,而 mold hot deformation also is Common types defect, hot deformation 会导致工 parts method more good use,甚至 to parts 直接报 waste, is can more good manufacturing parts,我们 in mold hot process 时, need good anti deformation as, its has anti measures main/primary has below/following types methods.

        1, material selection. for precision complex mold selection good micro deformation mold 钢如空淬钢), for carbon material 偏析严峻 mold 钢应进行公道铸造并进行调质 hot 处理, for relatively large and method mold can solid solvent di fine hot 处理.

        2, mold structure design need 公道, thick thin need 太悬殊, outer need for 称, for/regarding deformation relatively large mold need deformation 规律,预留 processing amount, for/regarding large type, precision complex mold can using/adopting combined structure.

        3, precision complex mold need 进行预先 hot 处理,消 remove machine processing process in generate residual stress.

        4, selection add hot temperature degree, control add hot speed degree, for/regarding precision complex mold can 采取缓 slow add hot, preheating and other add hot methods decrease/reduce mold hot deformation.

        5, in ensure mold hardness conditions lower,尽 amount using/adopting cold, separation grade cooling or temperature process.

        6, for precision complex mold, in front can lower,尽 amount using/adopting true add hot and rear deep cold 处理.

        7, for precision complex mold can using/adopting hot 处理, hot 处理, nitrogen hot control mold degree.

        8, in mold 砂眼, gas 孔, abrasion loss and other defect 时, selection cold machine and other hot effect/influence small equipment 以避免修补 process in deformation generate.
